Systems, implants, tools, and methods for treatments of pelvic conditions
View Patent ↗Described are various embodiments of surgical procedure systems, devices, tools, and methods, useful for treating pelvic conditions such as vaginal prolapse and other conditions caused by muscle and ligament weakness, the devices and tools being useful for transvaginally accessing a posterior region of pelvic anatomy, and related methods.
1. A medical apparatus for a sacrocolpopoxy, the medical apparatus comprising:
an expansion member including a tube, the tube having a distal end defining a distal end opening, and a proximal end defining a proximal end opening, the tube defining a lumen extending between the distal end opening and the proximal end opening, the distal end including a slant such that the expansion member has a first side and an opposing second side in which the first side has an overall length different than an overall length of the second side; and
an introducer configured to be inserted into a body of a patient via a vaginal or abdominal incision, and advanced to a region of a sacrum, the introducer being a device that is physically separate from the expansion member, the introducer including a first panel, a second panel, and a flexible member connected to the first panel and the second panel at opposing upper and lower edges of the first panel and the second panel, the introducer having a collapsed configuration in which the first panel is disposed on top of the second panel with the flexible member folded between the first panel and the second panel, and an expanded configuration in which the first panel is disposed away from the second panel,
the expansion member is configured to be inserted between the first panel and the second panel when the introducer is in the collapsed configuration to move the introducer from the collapsed configuration to the expanded configuration, wherein the expansion member, when inserted between the first panel and the second panel, is configured to drive the first panel and the second panel away from each other with the flexible member extending between the first panel and the second panel.
2. The medical apparatus of claim 1 , wherein each of the first panel and the second panel is flat.
3. The medical apparatus of claim 1 , wherein the tube is cylindrical.
4. The medical apparatus of claim 1 , wherein the expansion member includes a light along a length towards the distal end of the expansion member.
5. The medical apparatus of claim 1 , wherein the flexible member includes a flexible plastic material.
6. The medical apparatus of claim 1 , wherein the flexible member includes a fiber sheet material.
7. The medical apparatus of claim 1 , wherein the introducer is configured to be inserted into the body of the patient via the abdominal incision when the introducer is in the collapsed configuration.
8. The medical apparatus of claim 1 , wherein a distal end of the introducer is configured to deflect a sigmoid colon of a sacral promontory and move to a location over the sacral promontory to provide access to the sacral promontory.
9. The medical apparatus of claim 1 , wherein the medical apparatus is configured to push a bowel away from the sacrum to create a bowel-free access channel from an introitus to a sacral promontory when the introducer is moved from the collapsed configuration to the expanded configuration.
10. The medical apparatus of claim 1 , wherein the slant includes a taper configured to match a shape of the sacrum of the patient.
